Personal Verification/Identification via Analysis of the Peripheral ECG Leads: Influence of the Personal Health Status on the Accuracy

Table 1

Verification/identification accuracy calculated over the training database: selected threshold value (VerTHR), sensitivity, specificity, and value of the optimization criterion for person verification; accuracy for person identification (AccID), .
